Abstract

Geofluids, especially aqueous and carbonate ones have great influences on physicochemical properties of Earth materials, which in turn play significant roles in physical and chemical processes in the Earth's interior. Recent findings of close relationships between the loci of fluid liberation and those of seismicity in subduction zones have led many researchers to a speculation that just geofluids are the key player in seismic activities in subduction zones as well as in igneous activities. Geofluids in subduction zones also play critical roles in the global carbon cycle, which is one of the most important factors that control climate changes of the Earth's surface. This special issue "Geofluids" reports various aspects of aqueous, carbonate, and hydrocarbon fluids that reside in the shallow and deep interiors of subduction zones. Many of the six papers in this special issue were written by presenters in the session "Geofluids: the role of fluids in the Earth's interior" in the annual meeting of the Geochemical Society of Japan 2011. We hope that the papers in this special issue would provide readers with up-to-date understandings of the roles of geofluids in various activities and phenomena in this restless planet.
